I am building an RC car controlled by a Raspberry Pi, and I'm not sure how to go about setting up the power delivery circuit. I plan to power it with a 5200mAh LiPo battery, 2 cells, 50C rating @ 7.4v.
It has a JST-XH plug and Deans (T) connector for charging, and I would like to make it so that the vehicle can go to its designated charging place by itself and charge wirelessly. For this, I thought an easy way to do it is with a Qi wireless charger and a Qi receiver with USB-C.
With these in mind, I would need a circuit able to charge the mentioned battery without it catching fire, while also providing power to the Raspberry Pi while it stays in a low power state and the possibility to read battery percentage from it.
I have searched for something like this on the web but I didn't have any success. I have no background in electrical engineering, but I'm willing to learn if it means I have to design my own circuit.
I would also appreciate any feedback with my approach and any alternatives.
